The topic of this year's meeting focuses on "green industries" and the opportunities they offer to the developing countries under the current economic circumstances, which means, the role of industry in finding solutions for these countries in achieving their development objectives within a framework of environmental sustainability would be highlighted.
UNIDO's primary objective is the promotion and acceleration of industrial development in developing countries and countries with economies in transition and the promotion of international industrial cooperation.
The Organization believes that competitive and environmentally sustainable industry has a crucial role to play in accelerating economic growth, reducing poverty and achieving the Millennium Development Goals. The Organization therefore works towards improving the quality of life of the world's poor by drawing on its combined global resources and expertise in the following three interrelated thematic areas, including poverty reduction through productive activities, trade capacity-building and energy and environment.
